SPECIFICATION forming part of Letters Patent No. 697,763, dated April15, 1902.

Application filed January 15, 1900- Serial No. 1,471. (No model.)

To aZZ whom it may concern.-

Be it known that I, ADOLPH R. WIENS, a citizen of the United States, anda resident of Milwaukee, in the county of Milwaukee and State ofWisconsin,have invented certain new and useful Improvements in Brushes;and I do hereby declare that the following is a full, clear, and exactdescription'thereof.

My invention has for its main object to provide simple economicalone-piece multipletuft wood-back brushes proof against loss of tuftswhen subjected to conditions that cause shrink of the back material,said invention consisting in certain peculiarities of construction andcombination of parts, hereinafter particularly set forth with referenceto the accompanying drawings and subsequently claimed.

Figure l of the drawings represents a sectional view of a portion of aone-piece multiple-tuft wood-back brush and illustrates my improvements;Figs. 2 and 3, horizontal sections, respectively, indicated by lines 2 2and 3 3 in the first figure; and Fig. 4, an elevation of a tuft-securingplug constituting part of a finished brush.

Referring by letter to the drawings, A indicates a one-piece woodbrush-back and concentric with each tuft-socket b therein is anupwardly-extending recess 0 of less diameter than that of said socket,this recess being for the reception of a preferably wooden plug B,driven through the butt of a tuft C, constituting part of the brush.

In the manufacture of the brush the material, preferably bristles, foreach tuft is bunched and .wrapped at one end with fine cord 01, afterwhich it is dipped in a cement made to harden under pressure and thenset in a back-socket, this being common practice in the art ofbrush-making. The tuft is made to have snug fit in the socket, and beingpositioned a plug B is driven through its butt into the recess 0, thatextends upward from said socket concentric thereto, the plug BESS.

being preferably an ordinary shoe-peg l1aving a greater diameter thansaid recess. The plug not only compresses the tuft-butt in its socket,but it also carries some of the tuft material and cement into the recessextending from said socket to thereby anchor the tuft in the brush-back,it being understood that whether said plug be wood or metal,compressible or otherwise, there is a bind of said tuft material andcement in said recess to prevent said tuft from falling out when thereis shrinkage of the brush-back.

Excellent results are obtained by the utilization of shoe-pegs astuft-securing plugs,and by having the diameter of the pegs greater thanthat of the recesses c in the brush-back there is considerablecompression of said pegs with the tuft material and cement in said re-The shoe-pegs are also preferable as a matter of economy, they being acheap commodity well suited to my purpose.

The points of any kind of plugs being harder than the material in thebrush-back they will penetrate into the same, as herein shown, butotherwise they will be blunted by contact with said material.

Having thus described my invention, What Iclaim as new, and desire tosecure by Letters Patent, is-- A multiple-tuft brush having a one-piecewood back provided with a recess back of each tuft-socket incommunication therewith but of less diameter than the same, and a plugdriven through the tuft-butt in each socket with some of the tuftmaterial and its binding-cement into the adjacent recess.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Wiscousin, in thepresence of two Witnesses.
